Mounted in the high-side refrigerant circuit, it continuously monitors system pressure and opens the circuit to protect the compressor when pressure exceeds a safe threshold. When this switch trips or fails, the unit will lock out on a high-pressure fault, short-cycle, or simply refuse to cool — leaving you with a warm building and an active fault code. Replacing it with a genuine OEM part ensures the exact factory trip point is restored.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens (cuts out) at \u003cstrong\u003e395 PSI\u003c\/strong\u003e | Closes (resets) at \u003cstrong\u003e295 PSI\u003c\/strong\u003e | 1\/8\" NPT thread connection | 240 VAC rated | SPST normally-closed | Sensata PS80-03-0018 platform | Replaces: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, HK02ZA501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier switches are factory-calibrated to ±1% PSI tolerance at the specified trip point. Aftermarket substitutes can drift 5–10%, risking nuisance trips or, worse, compressor damage from under-pressure protection.
